SPECIFICATION forming part of Letters Patent No. 650,896, dated June 5,1900. Application mea April '26, 1899. serai No. 714,570. (No man.)

To all whom it may concern/.-

Beit known that I, JOSEPH M. GREEN, a citizen of the United States,residing at Mill Creek, in the county of rSalt Lake and State of Utah,have invented certain new and useful Improvements in Pumps, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

This invention has relation to improvements in pumps; and it consists inthe novel construction and combination of parts of .which it iscomposed, all as will be hereinafter fully explained, and particularlypointed out in the appended claim.

The annexed drawings, to which reference is made, fully illustrate myinvention, in which- Figure l represents a face View, partly in section,of my device. Fig. 2 is a plan view, having the frame, pitmen, pistons,and eccentrics removed. Fig. 3 is a vertical transverse sectional view,and Figs. tand 5 are sectional views of the eccentric.'

Referring by letter to the accompanying drawings, A designates thepuxnp,'comprising a series of cylinders a, that are cast integral,having a plate t), an upper plate B, a top plate e, and a bottom platef', provided with cups g', perforated at their lower end and providedwith valves c, pistons secured to the lower end of each piston-rod a',and an offset q', having channels leading to a reservoirs', providedwith valves, all of which constitute the pump proper.

B designates the upper plate of the pump, and e is the top or cap plate,having the stuffing-boxes f for the piston-rods a', and said top plateis secured in position upon the cylinders by the rods- 7c', passingthrough lugs on the plate B and through perforations in the top plateand lower plates b and f and secured by nuts l', thus firmly securingthe cylA inders between said upper and lower plates.

Above the cylinders is mounted a frame C, consisting of the end castingsh h, which are bolted to the top plate through their anges z' 'L' andthe end flanges j j of said plate. This frame comprises the end castingsaforesaid and two parallel horizontal bars k k, that are bolted at theirends l Z to the top flange m of each end casting.

Above the frame and the cylinders is mountpasses through a correspondingopening z in the piston-rods a', and the same is secured in positionupon said rods by a nut b' upon the screw ends o of the portion y, whilethe opposite end is provided with a screw end d', upon which a nut e' issecured, whereby the lower end of each pitman is pivoted. The pistonsare constructed with vertical openings m', above which is a valve n',that plays loosely upon the piston-rods, and a packing 0 is interposedbetween the upper and lower 'plates comprising the piston. Each of thesecylinders communicate with a reservoir bya passage p' in an offset'q,forming a part of said cylinders, andin the top of this offset arevertical openings r', providing a passage from said cylindersto achamber or reservoir s', that provides for the How of liquids from thecylinders. The'outlet-passages entering this reservoir are each providedwith an Aindependent valve t, which operates only with the y pistonchamber connected therewith through thispassage.v This reservoir has itsoutlet at the top, and the vertical movement of the piston-rods whichliftthe liquid forces the latter through the channels into thereceiving-,chamber and out'the opening or outlet. The upper portion ofeach piston-rod passes through a guide-openin g u in the crossbars o',which are bol'ted'atw to the parallel bars ofthe frame. Y

In operation the shaft n is set in motion, thus carrying with it theeccentrics, which operate thefpiston-rods, the pistons drawing the waterthrough the lower plates "into the cylinders, where itis lifted andforced through the passages into theV reservoir and through the outlet,and a pump as herein described is durable and readily taken apart forstoring or shipping and at the same time cheap to manufacture.

Having thus described my invention, what IOO I claim, and desire tosecure by Letters Patent, is

The Within-described pump, comprising the series of cylinders, havingthe oiset and formed of a single piece, the lower plate provided withthe perforated cups and valves o, plates b, B, top plate e, the pistons,having the perforations and formed of two parts, having the packing, andthe valve n; the reservoix` mounted upon the offset and communieatingwith the cylinders by the channels p', and the Valves t', arranged abovesaid channels and Within the reservoir; the pistonrods,having theopenings z, the Wedge-shaped blocks or arms y, the pitmen and frame,composed of the end standards, side bars and cross-bars o', and theeeeentries, mounted on the shaft a, all as shown and described.

In testimony whereof I have affixed my signature in presence of twowitnesses.
